Method Details

visit

public final void visit(Node node)

Tries to invoke (via reflection) the appropriate visit(...) method defined in a subclass. If there is none, it just calls the fallback() routine.

Parameters:

node - the Node to "visit"

recurse

public final void recurse(Node node)

Just recurses over (i.e. visits) node's children

Parameters:

node - the node we are traversing

fallback

public void fallback(Node node)

If there is no specific method to visit this node type, it just uses this method. The default base implementation is just to recurse over the nodes.

Parameters:

node - The node we are currently traversing
